(a) Cyclic voltammogram of CuNPSD for different scanning rates: 10–100 mV s−1 (KCl = 1.0 mol L−1, pH = 7.0). (b) Linear dependence of the anodic and cathodic current intensity with the square root of scan rate (peak I). (c) Linear dependence of the anodic and cathodic current intensity with the scan rate (peak(II)).
